GENERAL HISTOLOGY

Detailed explanation-1: -Pancreatic acinar cells are classical exocrine gland cells. The apical regions of clusters of coupled acinar cells collectively form a lumen which constitutes the blind end of a tube created by ductal cells-a structure reminiscent of a “bunch of grapes”.

Detailed explanation-2: -The pancreatic acinar cell is the functional unit of the exocrine pancreas. It synthesizes, stores, and secretes digestive enzymes. Under normal physiological conditions, digestive enzymes are activated only once they have reached the duodenum.

Detailed explanation-3: -Acinar cells are exocrine cells because they use a duct to secrete and release substances. The pancreas also has endocrine cells that release hormones directly into the blood.

Detailed explanation-4: -An acinus (/ˈæsɪnəs/; plural, acini; adjective, acinar /ˈæsɪnər/ or acinous) refers to any cluster of cells that resembles a many-lobed “berry, ” such as a raspberry (acinus is Latin for “berry").

Detailed explanation-5: -The cells are located in glands in the lining of the fundus, the part of the stomach that bulges above the entrance from the esophagus, and in the body, or principal part, of the stomach.
